The Czech Republic, which currently holds the rotating presidency of the European Union, called on Saturday (17) for the creation of an international tribunal for war crimes, after the discovery of about 450 bodies buried in a mass grave on the outskirts of Izyum, Ukraine. “In the 21st century, these attacks on the civilian population are unthinkable and heinous,” Czech Foreign Minister Jan Lipavsky said on Twitter. “We must not ignore it. We are for the punishment of all war criminals. I call for the speedy establishment of a special international court that will prosecute the crime of aggression.” Ukrainian President Volodymyr Zelensky said some of the bodies found this week had "signs of torture". Zelensky accused Russia of "cruelty and terrorism". Children's bodies were also found. Video:
